When we first happened upon a picture of this cake, we couldn’t believe it was real. Was it a fruit? Gelatin? Turns out that this striking, otherworldly concoction is Vietnamese Pandan Honeycomb cake. Pandan – a flavor not often seen in American baking – is a tropical plant from Southeast Asia with edible leaves that impart the flavor and green color to this unusual cake. You can find pandan extract in many larger SE Asian groceries or online. The main base ingredient of this cake is tapioca flour, which leaves a chewy texture in the middle, much like pão de queijo. Julesfood, Danang Cuisine, and Runaway Rice have similar recipes for Pandan honeycomb cake. The Spice of Life takes it one step further, and uses whole pandan leaves to supplement the flavor of the pandan extract, and while it seems a little difficult, the payoff is big!
